    Simple CBM calculator for shipping and freight▲5

    Hi HN Just sharing a small tool I built: https://cbmcalc.com It calculates CBM (cubic meters) for shipping cartons, pallets, or multiple boxes.

    Measure CO2 emissions of your APIs▲20

    Have you ever wondered about the carbon footprint of your API? This week, the 27th climate summit takes place in Egypt. This inspired us to draw attention to the emissions produced by our online behaviour. We introduced some CO2-related features to our API testing tool: - Calculate carbon emissions of an API call - Set up a check to validate that your API endpoint doesn't cross the limit when it comes to emissions - Test all your API endpoints and get an approximate calculation of your API emissions in total We hope that by using these features, you will become more aware of the carbon…

    Bend 2.0 API for transaction enrichment/CO2e estimates▲8

    Heyy HN. We’re celebrating 2 years of Bend’s existence as a company and we’ve launched a new API to help you understand the climate impact of business activity, and/or embed climate data in your application. For most companies, 80% of your emissions are from the goods and services that you buy. Unless you’re running a power plant or an airline, odds are you’re not directly combusting lots of fossil fuels. But literally everything we buy has some upstream climate impact, whether it’s the flights and Ubers that we purchase, or our AWS bills (that run on grids powered by natural gas), all…
